invention relates to aloe k foran anti-skid chain, the general object gof the invention being to provide means whereby the free end ofeach side chain of the ant1-,

'skid 'deviceis positively locked tothe other end so that :there is no danger of the parts becoming detached and "there are "no prov ij'ecting parts to strike ob ects which might act to unfasten the device.

This invention also consists 'in certain other features of construction and in the combination and arrangement of the several parts, .to be hereinafter fully described,

illustrated "in the accompanying drawings and specifically pointed out in the appended;

claims. I u In describing theinventlon 111 detall, reference will behad to the accompanying I pointed member used as a fulcrum drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is an elevation of the devlce, showing the same in use. 7

Figure 2 is an edge view thereof. Figure 3 is an edge view showing how a pointed member is used to unlock the device. Figure 4 is an elevation. with the pointed ,member in section.

Figure 5 is a longitudinal sectio nal view showing how the pointed member moves the inner part of the device to a position where it can be swung to unlocking position.

Figure 6a is a view similarto' Figure 5, but showing the inner member in looking position.

.Figure 7 is an elevation with the inner of the pointed memmember B, the outer member being of channel shape in cross section to receive the in ner member. Said outer member has one of the member A "is the outer end of mg the member 7 together, a link of the view of the end enlarged, as shown'at 1', with a rivet 2 passing through the enlargement and through therlinks which with the end link- 4 p of each side chain of :the anti-skid device;

The inner member B is formed with a hook at each mediate its ends, .these hooks beingconnected'with the same edgeof the member.

member B toward the hook 5. When the device is to be opened, the pointed member is placed in the slot 13 so asto force the member B to the left in Figure 1, so that the member can then be swung outwardly to release the link of the side chain.

The member 12 is provided with a notch 13 which is adapted to be placed in engagement with the hook 8 so that the member 12 can act as a lever to facilitate thestretching of the side chain by the turning move-J ment of the member B, as shown in Figure 7.

From the foregoing it will beseen-that the device positively locks theends oi the side chain together so that there is no danger oi the ends of thechain becoming separated. and as the member B has its ends entirely enclosed by the member A, there are noprojections for striking objects which might act to unlock the .device and in order to unlock the device, thememberQB must be moved longitudinally with considerable force before it can be swung outwardly to release the link ofthe side chain.
